TECHNICAL FIELD

The present invention relates to a novel oxopyrazine derivative or a salt thereof, a herbicide containing the same as an active ingredient, and a method of using the same.

BACKGROUND ART

Several compounds among the 1,3-cyclohexanedione derivatives which have been acylated at the 2-position with an arylcarbonyl group, have already been commercially available as agrochemicals. For example, mesotrione is attracting public attention as a foliar applied herbicide for corn having a new mechanism of action. A 1,3-cyclohexanedione is a tautomer, which exists also as 1-hydroxycyclohexene-3-one which is an enol form thereof, and this derivative has been developed as a compound for various agrochemical uses.

For example, a derivative having the aryl group of the arylcarbonyl group substituting at the 2-position changed to various heteroaryl or cycloalkyl groups such as pyrazine (see, Patent Document 1), a derivative having the 1,3-cyclohexanedione ring fused at the 4- and 5-positions with a cyclopropane ring (see, Patent Document 2), a derivative having the arylcarbonyl group at the 2-position changed to a pyrimidin-5-ylcarbonyl group derivative (see, Patent Document 3), a derivative having the arylcarbonyl group at the 2-position changed to a pyrazin-2-ylcarbonyl group derivative (see, Patent Document 4), a derivative having the arylcarbonyl group at the 2-position changed to a 1,2,3-thiadiazol-5-ylcarbonyl group derivative (see, Patent Document 5), derivatives having the arylcarbonyl group at the 2-position changed to a pyridinecarbonyl group derivative (see, Patent Documents 2, 6, 7, 8, 9 and 10), derivatives having the arylcarbonyl group at the 2-position changed to a quinolinecarbonyl group derivative (see, Patent Documents 11 and 12), a derivative having the arylcarbonyl group at the 2-position changed to a heteroarylcarbonyl group formed from a benzazole (see, Patent Document 13), a derivative having the arylcarbonyl group at the 2-position changed to an azolecarbonyl group derivative formed from an 1,2-azole (see, Patent Document 14), and the like have been reported. Furthermore, derivatives in which the 4-position and the 6-position of the 1,3-cyclohexanedione ring are crosslinked by an alkylene group such as an ethylene group, have also been reported (see, Patent Documents 8, 11, 12, 13, 14, 15 and 16). In addition, it has also been reported to have a 3,5-cyclohexanedione-1-thione ring in which the 5-position of the 1,3-cyclohexanedione ring has been changed to an oxo group, and the 1-position has been changed to a thiocarbonyl group (see, Patent Document 17).

As such, a large number of cyclohexanedione compounds having herbicidal activity have been reported, but there is no known cyclohexanedione compound having a dihydropyrazine ring substituted with an oxo group or a thioxo group (in the present specification, these may be generically called (thio)oxo), such as the compound of the present invention represented by the following formula [I].

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention

As discussed in the above, 1,3-cyclohexanedione compounds substituted with a specific heteroarylcarbonyl group are known to have an herbicidal activity, but since these compounds need to be applied in high doses, they are not satisfactory as herbicides. Thus, there has been a demand for the development of a herbicide showing excellent properties in lower doses.

The present invention has been achieved under such circumstances, and an object of the present invention is to provide a compound having a herbicidal activity which has no drug-induced damages against useful plants and useful crops, and can control various weeds growing in upland fields, orchards, paddy fields and non-agricultural lands at low doses, and a herbicide containing the compound.

Means for Solving the Problems

In order to achieve the above-described purpose, the inventors of the present invention devotedly conducted research on the chemical structure and herbicidal activity of cyclohexanedione compounds. As a result, they found that a cyclohexanedione compound having a pyrazine ring substituted with an oxo group or a thioxo group can control various weeds growing in upland fields, orchards, paddy fields and non-agricultural lands for a long time, and exhibits high safety against useful plants, useful crops and the like, thus completing the present invention.

Thus, the present invention is characterized in that for a 2-heteroarylcarbonyl-1,3-cyclohexanedione compound having a herbicidal activity, a 2-(thio)oxopyrazin-3-yl group which may be substituted, and preferably a 2-(thio)oxobenzopyrazin-3-yl group which may be substituted or a 2-(thio)oxopyridopyrazine-3-yl group which may be substituted, is used as the heteroaryl group.

Reference Example 1 (Production Intermediate) Production of 1-methyl-2-oxo-1,2-dihydroquinoxaline-3-carboxylic acid (Compound No. of Production Intermediate: V-2) (1) Production of ethyl 1-methyl-2-oxo-1,2-dihydroquinoxaline-3-carboxylate

4.0 g (18.3 mmol) of ethyl 2-oxo-1,2-dihydroquinoxaline-3-carboxylate was dissolved in N,N-dimethylformamide (100 mL), and under a nitrogen stream, 0.81 g (20.3 mmol) of 60% sodium hydride (oily) was added thereto, while maintaining the liquid temperature in the range of 5° C. to 10° C. After stirring the mixture for one hour at room temperature, 3.9 g (27.5 mmol) of iodomethane was added dropwise to the reaction solution. The mixture was stirred for a day at room temperature, and then the reaction mixture was poured into water, and extracted with ethyl acetate. The organic layer was washed with water and a saturated aqueous solution of sodium chloride, and dried over anhydrous sodium sulfate.
